Delphi Process In preparation for the first Delphi exercise, a list of questions was produced from the academic literature, webbased sources and interviews with experts. These questions were structured into broad dimensions and a draft questionnaire piloted. A final list of 73 questions formed the basis of the first Delphi survey. Participants were asked to grade the perceived importance of each question for inclusion in HTA reports on new prenatal genetic tests (4 = Essential; 3 = Desirable, but not essential; 2 = Useful but should not be required; 1 = Of little/ no importance; 0 = I have no basis for judgement). Secondly, they were asked to indicate whether a question should be addressed during test development or whether the question could be addressed later once the technology is ready for implementation. Finally, Panel members were encouraged to identify any other questions which appeared to be missing from the initial list. For copy of questionnaire, see Annex 1: Delphi Round 1 Questionnaire. Respondents were also asked to provide personal details to give some indication of their HTA experience and specialist expertise. Analysis of responses demonstrated that SAFE Delphi panel members represent a highly experienced, multidisciplinary international group of experts with the knowledge required to define which key questions should be addressed in HTA reports on new prenatal genetic tests. Delphi Responses Responses were received from 77/90 (86%) of Panel members. These were analysed with a cut-off of 75% (±3%) applied as an indicator of Panel consensus for all questions. Thus, any question which three out of four respondents rated as essential or desirable was retained, whilst those not achieving this level of agreement were provisionally excluded. In addition, mean scores were also calculated (excluding 0 = I have no basis for judgement) for each question. A mean score >3.25 ± 0.05 was taken as an indication that the Panel had identified a particular question as being of the highest priority to address in HTA.
